Additional researched vinca alkaloids include vincaminol, vineridine, and vinburnine. Vinpocetine is a semi-synthetic derivative of vincamine (sometimes described as "a synthetic ethyl ester of apovincamine"). [14] Minor vinca alkaloids include minovincine, methoxyminovincine, minovincinine, vincadifformine, desoxyvincaminol, and vincamajine ...
Vincamine is a monoterpenoid indole alkaloid found in the leaves of Vinca minor (lesser periwinkle), comprising about 25–65% of its indole alkaloids by weight. It can also be synthesized from related alkaloids.
The alkaloids are a large group of natural products which are classified according to the part-structure which members of a particular group contain. Akuammicine is a monoterpene indole alkaloid of the Vinca sub-group which shares a common biosynthesis with other members, namely that they are derived from strictosidine.
Catharanthus roseus, known formerly as Vinca rosea, is a main source of vinca alkaloids, now sometimes called catharanthus alkaloids. The plant produces about 130 of these compounds, including vinblastine and vincristine, two drugs used to treat cancer. [8] [9] [10] [11]
Vinca alkaloids were originally manufactured by extracting them from Catharanthus roseus (Madagascar Periwinkle). [1] Podophyllum spp. Two chemotherapy drugs, etoposide and teniposide, are synthetic chemical compounds similar in chemical structure to the toxin podophyllotoxin which is found in Podophyllum peltatum (May Apple).

Akuammine (vincamajoridine [2]) is an indole alkaloid. It is the most abundant alkaloid found in the seeds from the tree Picralima nitida, [3] commonly known as akuamma, comprising 0.56% of the dried powder. It has also been isolated from Vinca major. [2]
